ABSTRACT:
The invention relates to a sound dampened automatic hand firearm provided with silencing means for the firing of projectiles at a muzzle velocity in the subsonic speed range. In order to reduce also the breechblock noise during shot release, in addition to the muzzle noise and the projectile boom, a locking lever (18) is provided for locking the closed breechblock during discharge of the weapon. Preferably, the locking lever (18) is pivotable about an axis (19) oriented transversely to the barrel axis (24) and is held out of engagement by a spring (20). Associated with the trigger system is a catch (15) which causes the locking lever (18) to be pivoted into the locking position as the trigger (6) is being pulled. The catch (15) is pivotably mounted on the trigger (6).
